CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 287,385, dated October 23, 1883,

Application filed September 4, 1883. (No model.)

To all whom, t may con/cern:

Be it known that I, CONRAD LUTHER, acitizen of the United States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented a new and useful Oar- Coupling of which the following is a specification, reference being had to the accompanying drawings.

This inventionrelates to car-couplings; and it has for its object to provide means possessing superior advantages in point of simplicity, durability, convenience, inexpensiveness, and general efficiency.

To this endit consists in certain details of construction and combination of parts, as hereinafter fully set forth, and particularlypointed out in the claims. In the accompanying drawings, Figure l is a perspective view of my improved car-coupling. Fig. 2 is a longitudinal vertical section of the same. Fig. 3 is a detail view of the combined coupling hook and link.

Like letters refer to corresponding parts in the several figures.

Referring to the drawings, A designates the draw-head, provided with a mouth or recess, B, and in the rear of said recess is a slot, O, in which the end ofthe combined coupling hook and link is pivoted by means of swingving arms D D, the latter extending through the draw-head.

E designates the combined coupling hook and link, formed in one piece of metal, the link being shown at F in the usual form, while the hook G projects from the inner end of the link in a downward direction. The inner end, H, of the combined link and hook is formed solid, and is mounted upon the swinging arms, so as to turn when said arms are moved upward or downward. The end of the swinging arms which projects through the drawhead is provided with a split key, by means of which the arms are held in the draw-head.

It will be seen that the inner end of the coinbined couplinghook and link works in the slot C, while the front end thereof works vertically in the recess B.

The operation and advantages of my invention are obvious,'and need not be particularly recited here.` By means of the swinging arms 5o arms to perform this action, since a chain, f

rope, or rod may be passed through an opening in the upper face of the draw-head', so as 55 to connect with the couplingV devices, and thus form a good substitute for said arms.

The coupling of the devices is automatic, the hooks vdropping into the links, one of the hooks passing upwardly through the link of 6o the adjoining car, while the other hook passes downwardly through the corresponding link.

It will be seen that when one of the sets of coupling ydevices breaks another set will remain to couple by, since the double construction'of hook and link affords means for this purpose. The coupling above described is simple and efficient, andiby means of the double construction it will prove of incalculable value in its attachment to cars.

Having described my invention, I claim as newl. In a car-coupling, the combination, with the draw-head, of the combined hook and link, pivoted at its rear end, H, by means of swinging arms D, which pass through the drawhead, arranged and operating for the purpose set forth.

2. In a car-coupling, the combination, with the draw-head, of the combined coupling hook and link, pivotedatits rear end, H, swinging arms D, on which said coupling hook and link is mounted, slot C, and recess B in the draw-head, to permit the action of the coupling devices, the link extending outward in the usual manner, while the hook projects downwardly through the link, from the inner end of the same, as set forth.

In testimony that I claim the foregoing as my 9o own I have hereto affixed my signaturev in presence of two witnesses.
